The Frequency of Emergence Delirium in Children Undergoing Outpatient
Anaesthesia for Magnetic Resonance Imaging
Abstract
Background: The aim of this study was to investigate the effect on the
occurrence of emergence delirium of propofol and ketofol with intranasal
dexmedetomidine and midazolam applied as premedication to paediatric
patients during magnetic resonance imaging (MRI). Methods: The study
included children aged 2-10 years who received sedation for MRI,
separated into four groups. Group MP received intranasal midazolam (0.2
mg/kg) for premedication and IV propofol (1 mg/kg) as the anaesthetic
agent. Group MK received intranasal midazolam (0.2 mg/kg) for
premedication and IV ketofol (1 mg/kg) as the anaesthetic agent. Group
DP received intranasal dexmedetomidine (1 mcg/kg) for premedication and
IV propofol (1 mg/kg) as the anaesthetic agent. Group DK received
intranasal dexmedetomidine (1 mcg/kg) for premedication and IV ketofol
(1 mg/kg) as the anaesthetic agent. The Paediatric Anaesthesia Emergence
Delirium (PAED) scale was used to evaluate delirium. A PAED score ≥ 10
was accepted as delirium. Results: The need for additional anaesthetic
was highest in Group DP at 94.3% and lowest in Group DK at 14.3%. The
mean Aldrete and PAED scores were lower and the length of stay in the
recovery room was shorter in Group DP than in the other groups. Delirium
only developed in two patients in Group MP (5.7%) at 5 mins after
anaesthesia. Conclusion: In our study, delirium was seen at a very low
rate only in the Group MP and it is difficult to say the best
combination in terms of delirium frequency with this result.
